No, they won;t.
Ortiz is effectively done. He has no ( I mean NO) bat speed any more. I'm a Sox fan and I watch every game. You'd be very lucky to see end of the year numbers for Ortiz at:
.240, 10 HR, 50 RBI
Really, that's a best case scenario.
DiceK isn't worht it either, he is just a big name. His K numbers will be pretty good, but everything else will absolutely MURDER you. Especially hsi WHIP, as we all know.
I'd expect an ERA of 4.30, 150 Ks, WHIP of 1.40 (at least). You can do better than that.
